gui-sdl has its own copies of all of the get_unit_info_label_text2()
and tile_get_info_text() so it can just add one extra linebreak. This
is bad for maintainability. When ever those functions change, somebody
has to make separate fix for gui-sdl.
This patch makes linebreak behavior parameter of common
get_unit_info_label_text2(), so also gui-sdl can use it. gui-sdl
copies of these functions removed.
That linebreak was only difference according to comments, not sure
that other changes have not crept in. There were no comments about
forking these functions more in the future.
